320-Gb/s Single-Polarization DPSK Transmission Over 525 km Using Time-Domain Optical Fourier Transformation

A 320-Gb/s single-polarization differential phase-shift keying transmission is successfully demonstrated over a 525-km straight transmission line using time-domain optical Fourier transformation (OFT). The tolerance to higher order polarization-mode dispersion is greatly improved and long-term stable transmission performance is achieved with OFT.
